Services offered:

Tank Calibrations:

PM provides tanks calibration, commonly known

as “Tank Strapping”. This is the term applied to

the procedure for the measurement of storage

tanks, barges, ships, and/or any liquid bulk

container. These measurements provide the

necessary dimensions for the calculation of

capacity or “strapping tables”. Our service meets

& exceeds all API Standards for tank calibration

Considerations for calibrating a tank:

� New Construction.

� After any structural modifications.

� In conjunction with an API 653

inspection.

� Minimal 15 year intervals as

recommended by API.

Considerations for re-computation of capacity

tables:

� Change in service products reflecting different gravities.

� Change in IFR weight or leg position.

� New gauge position or new gauge height

PM can customize charts to meet your needs. Options include:

We have over twenty one years experience in the

accurate field measurements and

Charts/tables will be completed and delivered electronically the same day. N

UTI Shell/Floor/Roof Readings:

Digital ultrasonic thickness testing is the measurement of the remaining wall thickness of pipelines,

tanks, or pressure vessels subject to internal corrosion.

High Level Alarm Verifications:

We know how crucial it is for tank owners &

terminal/project managers to know exact

their liquid levels are.

These levels are critical when trying to determine

such levels as the following:

� The high alarm level.

� The high-high alarm level.

� The (safe fill height).

� The overflow level.

� The deck damage level (The point at which

the secondary seal of the IFR will make contact

with the lowest fixed appurtenance (i.e., overflow

vents, foam chambers, rafters, etc.)

Gauge Tape Calibration/API-Certification:

API requires all gauge tapes used in the measurement of “custody transfer products” to be calibrated

at least once a year!

PM calibrates tapes by comparing the working tape at very specific designated intervals against our

“NIST” master tape. A very specific amount of tension is applied to both tapes on a flat surface. The

physical readings are taken and the variances are noted and recorded.

Page 4

The physical readings will be recorded and documented. The owner will be issued a “Certificate of

Calibration” for each gauge tape.

The “Certificate of Calibration is valid for one year as per API standards.

Tapes with accompanying certificates are considered “NIST” traceable and are accepted by API for

custody transfer measurements.

Our Certifications

Precision Measurement’s written policy & procedure manual for tank & tape

measurements assures all measurements are performed in a unified manner. All work

performed by PM is done in strict accordance with the latest American Petroleum

Institute (API) Standards, which includes the: Manual of Petroleum Measurements

Standards (MPMS), the International Organization of Standardization (ISO) and

(NIST).

Thank you for looking through just some of the services we offer. We can customize our services to fit

your exact needs and will work closely with you to get the project done.

If you have any questions at all, please feel free to give me a call anytime.

As always, I really do appreciate your business & loyalty!
